Abstract

Aim

To test a novel calcium silicate cement mixed with a water-based gel (NoeMTA Plus) with regards to chemical-physical properties and apatite forming ability.

Methodology

NeoMTA Plus (Avalon Biomed Inc. Bradenton, FL, USA; lot. 2014090301), and a commercial MTA-based material with similar properties (MTA Plus, Prevest Denpro Limited, Jammu, India; lot. 41001) were tested for ion-releasing ability, initial and final setting times, radiopacity, open and impervious porosity and apparent porosity, water sorption, weight loss, solubility, ability to nucleate calcium phosphates (CaP) after immersion in HBSS (Hank's Balance Salt Solution) by ESEM-EDX and Micro-Raman spectroscopy. The results were analyzed statistically with ANOVA test (P < 0.05).

Results

NeoMTA Plus had a prolonged setting time (315 min) and a satisfactory radiopacity (3.76 mm AL). Calcium and hydroxyl ion release was significantly greater and more prolonged in comparison with MTA Plus (P<0 .05="" ability="" after="" and="" both="" calcium="" confirmed="" esem-edx="" had="" hbss.="" high="" immersion="" in="" micro-raman="" mta="" neomta="" nucleate="" of="" on="" open="" p="" phosphates="" plus="" porosity="" solubility.="" surface="" the="" their="" to="" values="">

Conclusion

NeoMTA Plus is a new calcium silicate based cement for root filling with an adequate radiopacity and prolonged setting time. The ion release and CaP forming ability could increase stability of the root filling and promote endodontic and periodontal tissue regeneration, enhancing the bioactivity and biocompatibility of the material.
